Abstract:
PROBLEM TO BE SOLVED: To provide a device, a method and a system is preparation for decision and operation of a caller number by utilizing digit analysis. SOLUTION: A network interface receives an incoming message which has a received caller number and transmits an outgoing message. A memory stores plural digit trees for digit analysis and a plurality of available operations as a module of a database. A processor applies digit analysis of the received caller number to decide on pattern matching and decides a selected operation, conducts the selected operation with respect to the received call number to generate a corrected caller number. The processor instructs the network interface to transmit the corrected caller number included in the outgoing message, when the pattern matching is decided and instructs the network interface to transmit the received caller number included in the outgoing message, when the pattern matching is not decided.
Abstract:
The present invention provides a method involving a femtocell in communication with a secure core network such as an Internet Protocol Multimedia Subsystem (IMS) network. The method includes receiving, from the femtocell and at a first secure entity in the IMS network, a global challenge including information indicating a random number. The method also includes receiving an authentication response computed by a mobile unit based on the random number and the first key known by the mobile unit and not known by the femtocell. The method further includes determining, at the first secure entity, that the random number is a legitimate random number provided to the femtocell by the IMS network.

La presente invenci?n proporciona un m?todo que incluye una femtoc?lula en comunicaci?n con una red central segura tal como una red de Subsistema Multimedia de Protocolo de Internet (IMS, por sus siglas en ingl?s). El m?todo incluye recibir, de la femtoc?lula y en una primera entidad segura en la red de IMS, un desaf?o global que incluye informaci?n que indica un n?mero aleatorio. El m?todo tambi?n incluye recibir una respuesta de autenticaci?n computada por una unidad m?vil con base en el n?mero aleatorio y la primera clave conocida por la unidad m?vil y no conocida por la femtoc?lula. El m?todo incluye adem?s determinar, en la primera entidad segura, que el n?mero aleatorio es un n?mero aleatorio leg?timo proporcionado a la femtoc?lula por medio de la red de IMS.
Abstract:
An apparatus, method and system are illustrated which provide for calling party number determination and manipulation, utilizing digit analysis. One of the switch embodiments includes a network interface, a memory, and a processor. The network interface receives an incoming message having a received calling party numbe r and transmits an outgoing message. The memory stores, as a database module, a plurality of digit trees for digit analysis and a plurality of available manipulations. T he processor includes instructions to perform digit analysis of the received calling part y number to determine a pattern match and to determine a selected manipulation of the plurality of available manipulations, and to perform the selected manipulation on the received calling party number to form a modified calling party number. The processor includes further instructions, when a pattern match has been determined, to direct the networ k interface to transmit the modified calling party number in the outgoing message, and when a pattern match has not been determined, to direct the network interface to transmit the received calling party number in the outgoing message. The database module m ay be modified for calling party number format variability, such as for international use.
Abstract:
The present invention provides a method involving a femtocell in communication with an Internet Protocol Multimedia Subsystem (IMS) network. In one embodiment, the femtocell operates according to code division multiple access (CDMA) standards. The method includes receiving, from the femtocell and at a first secure entity in the IMS network, first authentication information generated by the mobile unit using a first random number broadcast by the femtocell in a global challenge. The method also includes receiving, from a second secure entity in the secure network, at least one security key formed based on the global challenge and second authentication information for uniquely challenging the mobile unit. In one embodiment, the second secure entity is a CDMA-based authentication server. The method further includes providing the security key(s) to the femtocell in response to authenticating the mobile unit based upon the second authentication information.
